Application ld ctober 29, 1919. Serial No. 334,181.

To all whom t may concern.'

Be itknown that I, RAY O. HOOKER, a citizen of the United States, residing at Utica,l in the county of Ness 'and lState of Kansas, have invented certain new and useful Improvements in a Machine-Gun, of which the following is a specification.

My invention relates to new and useful improvements in a machine gun and more particularly to a liquid fuel machine gun.

The principal object of the invention is the construction of a machine gun in which the bullet is discharged by the explosion of an internal combustion engine.

Another object of the invention resides in the provision of a ma azine for holdin a plurality of bullets an means for feeding the bullets to the proper position to be dis- A further object consists in the novel construction of a fuel chamber so that little space will'be required.

With these and other objects in View my invention consists in the novel details of construction and arrangement of parts which will be more clearly understood from the following specification andl drawings in which Figure 1 is` a longitudinal vertical section, parts being shown in elevation, and

Fig. 2 is a fragmental top plan.

In the drawings the numeral 1 indicates a plate or base supported upon the tripod legs 2. A second plate 3 is secured upon the plate or base 1 by means of a screw 4 and this plate 3 has a casting 5 formed on the top thereof. An internal combustion engine cylinder 6 is formed integralon the top of the casting 5 and has a water space 7 for cooling the engine.- The piston bore is indicated at 7 and is enlarged at the rear end to form the crank case 8. The crank is indicated at 9 and has the piston .rod 10 secured thereto in the usual manner; rIfhe piston 11 is connected to the opposite end of the piston rod and is adapted to reciprocate in the piston bore 7. A longitudinally extending groove 12 is formed in the piston bore so as to form a by-pass for the passage of the gas to be later described.

A fly-wheel 13 is secured on oneV end of the crank shaft 9 and a cam 14 is secured on the crank shaft between the cylinder 6 and the fly-wheel 13.A The purpose of this cam will be later described. The cylinder 6 is provided, on the underside, with a vertical opening to receive the loader 15.

This loader 15 is adapted to reciprocate ver- 20 which is adapted to engage the outer face of the cam 14. A spring 21 is secured to the top of the plate 3 at one end and the opposlte end 1s secured to the underside of the lever 7 at a point between the pivot point 18 and the link 15. The spring normally holds the link end of the lever 17 downwardly so as to hold the roller 20 into engagement with the cam 14.

The barrel is indicated at 22 and has the usual central bore 23. The central bore 23 is in alinement with an opening 24 in the end of the engine cylinder. The loader 15 1s adapted to have its upper end normally rest adjacent the opening 24 for a purpose to be later described. A casing 25 surrounds the barrel and the space between the casing and barrel forms a -fuel container. An opening is formed in the top of the casing 25 and is closed by means of a screwcap 26. Liquid is supplied to the fuel container by removing therscrew cap 26.

A carbureter 27 is secured to the end of the crank case 8 and has a branch 28 communicating with 'the crankrcase. The throttle valve 29 closes the communication between the branch 28 of the carbureter and the crank ease. An air inlet branch 30 is formed on the carbureter for admitting air thereto. An opening is formed in the underside of the casing 25 and a screw plug 31 is received therein. A pipe 32 leads from the screw plug to the bottom of the carbureter and is connected thereto at 33. The liquidv passes from the liquid container through the pipe 32 to the carbureter 27.

A passage 34 is formed in the engine cylinder 6 and extends downwardly at the rear end and terminates in an extension 5. A pipe 36'is secured to this extension 35 and receives a screw cap 37 on the lower end thereof. This pipe 36, together with the passage 34, Iforms a magazine for receiving the bullets 38. A follower 39 is placed in the magazine and is pressed by the spring 40. The follower 39 normally engages the last bullet and tends to force the bullets upwardly and toward the loader. By reference to Fig. 1 of the drawings it will be noted `that the passage 34 leads into the opening in which the loader operates.

A rear sight 41 is secured on the top of the engine cylinder and a forward sight 42 is secured on the upper faces of the casing 25.

From the above detailed description it is thought that the manner -of using my machine gun will 'be understood as well as the several advantages. Asstated in the objects of the invention the bullet is adapted to 'be discharged through the explosion ofthe internal combustion engine. As shown in Fig. 1 of the drawings the gas which has been drawn from the carbureter is under compression and will be exploded by the spark plug 43. The bullet 38, which s held on top of the loader, will be discharged through the bore 23 of the barrel 22. The piston l1 will be. drawn backward and allow the gases' which are in the crank ease to pass through the by-pass groove. l2 to the front of the piston. The piston will then start on its forward stroke and again compress the gases. It will be understood that on the forward stroke of the piston gas is sucked from the carbureter through the throttle valve. After the explosion takes place the rotation of the cam 14` will allow the spring 21 to draw down on the forward end of the lever 17 and thereby lower the loader 15. The spring 40 and follower 39 will force another bullet over the top of the loader and asthe loader is raised it will raise the bullet into the proper position to be discharged through the bore of the barrel. By having the fuel container around the barrel a very little eXtra space is required and all parts of the gun are held in compact form.

The foregoing description and the drawings have reference to what may be considered the preferred or approved form of my invention. It is to be understood that I may make such changes in construction and arrangement and combination of parts, materials, dimension, etc., as may prove eX- pedient and fall within the scope of the ap pended claims.

Having fully described my invention what I claim as new and desire to secure by Letters Patent is 1. A machine gun comprising a base, a cylinder supported on the base and having an opening in one end thereof, a carbureter secured to and communicating with the opposite end of the cylinder, a piston operable in the cylinder, a barrel secured to `the end of the cylinder and communicating with the openingtherein, a fuel chamber surrounding the barrel, means for feeding a bullet to the opening in the cylinder, and means for feeding fuel from the fuel chamber to with the opening therein, a fuel chamberA Vsurrounding' the barrel, a pipe leading from the fuel chamber to the carbureter, a piston operable in the cylinder, a magazine secured to the cylinder, a `breech block for feeding the bullets from the magazine to the opening in the cylinder, a lever pivotally connected to the base, a link connecting the breech block at one end of the lever, anda cam engaging the opposite end of the lever.

3. A machine gun comprising a base, a cylinder supported upon the base and having an opening in one end thereof, a carbureter secured to the opposite end of the cylinder and communicating therewith, a piston operable in the cylinder, a barrelconnected to the end of the cylinder and` communicating with the opening therein, a fuel chamber surrounding the barrel, a pipe leading from the fuel chamber to the carbureter, a bullet magazine secured to the cylinder, a vertically slidable breech block operable in the end of the cylinder for feeding the bullets to the opening, a lever pivotally connected to the base, a link connecting one end of the lever to the breech block, a rotatable cam for engaging the opposite end of the leverand a spring secured to the underside of the lever between the pivot point and the link end.

In testimony whereof I aiix my signature in presence of two witnesses.
